Setting up networking similar to VirtualBox

[Philip Andrews <pa...@Thunderhead.com>]

Hello List,

I've managed to get Cloudstack Mgmt and Host services running on my laptop and deployed a VM. The only way I could do this was to put all the IP addressing on the same 10.x.x.x network that my laptop was connected to for the internet.

I'd like to setup the machine so the VM's are on an internal 192.168.x.x network for all their IP addressing and NAT'd to the internet through the 10.x.x.x IP address.

Is there a way to do this without changing any of the routing/switching infrastructure my laptop is connected to? I have found several tutorials about doing this with vlan's and IP tables but I was unable to get them working.

Any help with documentation or configuration ideas would be greatly appreciated. This is for a test environment not production (obviously?).

Thanks,
-Phil

you'll probably need to have a couple interfaces (or bridges) say for
example Outside and Inside (where the guests will live). You'll need to
setup ip forwarding so that your traffic on inside gets routed out via
Outside. I've dont this a long while back but have since forgotten the
gritty details. You can google masquerading or ip forwarding... This
article rings a vague bell:

You might also want to ping the dev list, to see if there are any
useful
tips from the folks there.
